2966d28c32 Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

ba174a5e38 Back out all POSIXified *env() changes.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

17ebe40096 Implement rpmatch(), a semi-standard interface (as found on AIX, Tru64,
GNU) for determining whether a string is an affirmative or negative
response to a question according to the current locale. This is done
by matching the response against nl_langinfo(3) items YESEXPR and NOEXPR.

12eb46c8bb Change the definition of NULL on ia64 (for LP64 compilations) from
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
   by virtue of the generated code implicitly widens ints to longs and
   allows the use of an 32-bit integral type for 64-bit arguments.
   Subsequent arguments are passed onto the memory stack, which does
   not exhibit the same behaviour and consequently do not allow this.
   In practice this means that variadic functions taking pointers
   and given NULL (without cast) work as long as the NULL is passed
   in one of the first 8 arguments. A SIGSEGV is more likely the
   result if such would be done for stack-based arguments. This is
   due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
   exception of ia64, allow 32-bit integral types (specifically NULL)
   when 64-bit pointers are expected in variadic functions by way of
   how the compiler generates code. As such, code that works correctly
   (whether rightfully so or not) on any platform other than ia64, may
   fail on ia64.

To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.

This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...

d7875fc3b3 Don't blindly provide alloca() for all compilers -- it is too implementation
dependent.  Instead provide one for GCC & Intel's GCC copy and one for lint.
Anyone using any other translator tool needs to look closely at how that tool
can handle alloca.

6a66acb565 Replace our ancient dtoa/strtod implementation with the gdtoa
package, a more recent, generalized set of routines.  Among the
changes:
- Declare strtof() and strtold() in stdlib.h.
- Add glue to libc to support these routines for all kinds
  of ``long double''.
- Update printf() to reflect the fact that dtoa works slightly
  differently now.

As soon as I see that nothing has blown up, I will kill
src/lib/libc/stdlib/strtod.c.  Soon printf() will be able
to use the new routines to output long doubles without loss
of precision, but numerous bugs in the existing code must
be addressed first.

614b366763 Fixed namespace pollution and/or breakage of K&R and C90 support related to
the following functions in the following commits:
- atoll() in revs 1.23-1.25
- llabs() and lldiv() in revs 1.22
- strtoq() and strtouq() in revs 1.18
C99 functions must not be declared in C90/POSIX.1-1990 sections, and
"long long" must not be exposed to compilers that don't support it.

Fixed style bugs (mainly misindentation and disorder) related the
following functions in the following commits:
- atoll() in revs 1.23-1.25
- getprogname() in rev.1.21
- sranddev() in revs 1.19-1.20
- strtoq() and strtouq() in rev.1.13
- user_from_uid() in rev.1.1
Breakage of K&R and C90 support used to be avoided by conditializing the
"long long"s for strtoq() and strtouq() on __STRICT_ANSI__, but the
conditionals should have gone away in rev.1.13 when the "long long"s went
away (the problem was moved to the places that declare quad_t and u_quad_t).
